- COP-SKEWER FOR LOOM-SHUTTL'ES,

To allwhom it may concern;

Be it known that I, CHARLES F. ROPER, of Hopedale, county of \Vorcester, State of Massachusetts, have invented an- Improvement in Cop-Skewers for Loom-Shuttles, of which the following description, in connection with the accompanying drawings, is a specification,

like'letters on the drawings representing like parts. 1

Cop-skewers or fillingcarriers for loomshuttles have heretofore had their heads provided with unyielding ribs or rings which were adapted to enter grooves in springs oarriedby shdQtles-springs such as represented in United States Patent No. 538,507, dated April 30, 1895and-United States Patent No. 454,311, dated January 23, 1891, shows one old form of copskewer.

I In automatic looms-such, for instance, as the Northrop-the cop-skewers or fillingcarriers, as they are therein designated,- are transferred rapidly from the filling-carrier feeder intothe shuttle while the loom is in -motion, and much trouble has been experienced therein owing to. the rapid wearing awayof the grooves in the' shuttle-springs, that being due-t0 the hard unyielding rings surrounding the-head of the skeweror Iillingj carrier.

v --Thispresent inventionhas-for'its object the production of a, cop-skewer or filling carrierthe head of which shall becapable of yielding to a limited extent when. being .in-

"serted into the shuttle between the said rounded with a split ring of non-metallic masprings, such construction greatly reducing the wear of the shuttlerspring grooves. To efiect this improvement, the metallic head of the skewer --or filling-carrier has been surterial, preferablywood, and the head of the filling-carrier has -been provided with an, an-

.nular groove inwhic'h this split shell or cylinder is located,flthe shoulders of the groove preve nting longitudinalmovement of the split ring.

' The skewer-blade a may be of' usual con-- struction, and has secured thereto a metallic head a, provided at itsends with annular flanges-0t a A-non-metallic split shell or cylinder 1),

preferably of wood,- surroundsthe head a" between the flanges thereof, and it is annularly grooved, as at b, to fornrseatsfor the encircling metallic splitrings a, which enter the usualgrooves in the shuttle springsor jaws. These rings retain the non-metallic shell I) on the inetal head a, and when the springs the splitsh'ell, yielding slightly tothe pressure, thus greatly reduces the wear. on the sh uttle-springs.

filling-carrier is being forced into the shuttle I In Patent No. 454,811 referred to a' luetallic head is surrounded by a wooden ring,-

shell do 'not abut one against the other, and r therefore the shell has a capacity of yielding soniewhat under pressure put upon the metallic rings c. 3 v
